PHP 数组分页实现方法

在 PHP 中，可以通过数组切片和计算偏移量实现分页功能。以下是两种常见实现方式：

基础数组分页实现

function paginateArray($array, $page, $perPage) {
    $totalItems = count($array);
    $totalPages = ceil($totalItems / $perPage);
    $offset = ($page - 1) * $perPage;

    return [
        'data' => array_slice($array, $offset, $perPage),
        'total' => $totalItems,
        'per_page' => $perPage,
        'current_page' => $page,
        'last_page' => $totalPages
    ];
}

// 使用示例
$dataArray = range(1, 100); // 示例数组
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$perPage = 10;

$result = paginateArray($dataArray, $page, $perPage);

带样式分页链接生成

function generatePaginationLinks($currentPage, $totalPages, $url = '?page=') {
    $links = '';
    $range = 2; // 显示当前页前后页数

    for ($i = 1; $i <= $totalPages; $i++) {
        if ($i == $currentPage) {
            $links .= "<span class='current'>$i</span>";
        } elseif ($i >= $currentPage - $range && $i <= $currentPage + $range) {
            $links .= "<a href='{$url}{$i}'>$i</a>";
        }
    }

    if ($currentPage > 1) {
        $prev = $currentPage - 1;
        $links = "<a href='{$url}{$prev}'>&laquo; 上一页</a>" . $links;
    }

    if ($currentPage < $totalPages) {
        $next = $currentPage + 1;
        $links .= "<a href='{$url}{$next}'>下一页 &raquo;</a>";
    }

    return $links;
}

Laravel 风格分页实现

对于需要更完整分页功能的情况，可以模仿 Laravel 的分页器：

class ArrayPaginator {
    protected $items;
    protected $perPage;
    protected $currentPage;
    protected $total;

    public function __construct($items, $perPage, $currentPage) {
        $this->total = count($items);
        $this->items = array_slice($items, ($currentPage - 1) * $perPage, $perPage);
        $this->perPage = $perPage;
        $this->currentPage = $currentPage;
    }

    public function links() {
        $totalPages = ceil($this->total / $this->perPage);
        return generatePaginationLinks($this->currentPage, $totalPages);
    }

    public function items() {
        return $this->items;
    }
}
